FEED-WATER HEATER AND PU RIFIEI R.

sPEcIFIc 'rIoNformin ar of Letters Patent No. 741,502, iatea October 13, 1903;

Application filed October 30, 1902. Serial No. 129,473. (No model.)

To all whom it may concern:

Be itknown that I, R BERT WILLIAM J ONEs, a citizen of the United States," residing at'London, in the county of Madison and State of Ohio, have invented certain new and useful Improvements in Feed-Water Heaters and Purifiers; and I do declare the following to be va full, clear, and exact description of the inopen-exhaust heaters, in which the feed-f water for the boiler is heated by direct exposure to exhaust-steam'from an engine; and it consists in the peculiar construction and combination of devices hereinafter fully described and claimed.

The object of my invention is to provide a simple and compact feed-water heater of this class which is efficient in employing exhaust steam from an engine for heating'feed-water prior to its introduction into the boiler, in removing lime, magnesium, and other deleterious substances from the water, and also in filtering the same, so that it is purified while being heated for use in the boiler.

- In the accompanying drawings, Figure l is a vertical longitudinal sectional View of a feed-water heater and purifier constructed in accordance with my invention. Fig. 2 is a vertical transverse sectional view'of the same,

taken on the plane indicated by the line a a of Fig. 1. r

In the embodiment of my invention I provide a casing 1, which is here shown as elliptical in cross-section, but which may be of any suitable form, size, and construction.

The same is divided by a longitudinal parti tion-plate 2 into an upper compartment 3 and a lower compartment 4;. The longitudinal partition-plate forms the bottom of the upper compartment, and the same is inclined down wardly from its ends to,itscenter and provided at its center, which is its lowest level, with an overflow-pipe 5, the said pipe rising for a suitable distance above the lower portion of the said partition-plate and being pen at its upper and lower ends. The said partition-plate Or'bottom of the upper compartment and the said overflow-pipe constiment and causes the impurities in the water to be precipitated to the bottom 2, the water beingdrawn from near the level of the water at an elevated point by the overflow-pipe 5 and discharged therebyjrom theupper compartment into the lower compartment. In the upper compartment is a plurality of precipitate-troughs 6, which are longitudinally disposed and are also disposed at different elevations, one below another and adjacent to each other, so that water supplied to the uppermost trough willflow therefrom into each of the lowerjtroughs in succession.

Iu'the lower portion of'the lower compartment 4, atone end thereof, is a filtering-chamber 8. The same is in practice filled with sand, gravel, charcoal, or any other suitable filtering materialj That portion of the bottom of the lower compartment which is not occupied by the filtering-chamber 8 is covered by a grate-trap 9, which is a bottomless tray comprising a plurality of bottomless compartments 10, separated from each other by partition-plates 11, which connect the sides of the tray. The latter is removable from the lower compartment, and the precipitate-troughs 6, hereinbefore described, are alsoremovable from the upper compartment. The said compartments are each provided at one end with a manhole 12 and with a headplate 13 to form a closure therefor. The plates are secured on the open ends of the said compartments by any suitable means.

In the lower compartment 4 on the gratesupported by stands 15, having longitudinal'l side bars 16, and each of the lower precipil tate-trouglis is provided at its inner side with a hook 17 to engage one of said bars, and hence each of the precipitatetroughs, except the uppermost, is removable from the stands 15 at will. This construction enables either series of the precipitate-troughs to be removed either collectively or singly, as may be desired.

It will be understood from the foregoing that by this construction of the casing, the grate-trap, and the precipitate-troughs access may be readily attained to either compartment of the casing and to either or all of the precipitate-troughs and also to the gratetrap, so that the same maybe readily cleansed when it becomes necessary.

On one end of the casing in proximity to the filter-chamber 8 is a supplemental filterchamber 17. Communication is established between the said filter-chambers, as at 19, and preferably the exterior filter-chamber 17 is provided with a water-gage 20 and with a draw-off faucet 21,by which it may be drained. The same is also provided with a water-discharge connection 22, by which water after the same has been heated and purified in the heater and purifier may be supplied to the pump or boiler.

On one side of the casing, and preferably near that end thereof which is provided with manholes, is a condensing-chamber 23. A feed-water pipe 2% is coupled thereto near its lower side, and a pipe 25 leads from the upper end of said condensing-chamber and discharges into the upper side of the upper compartment 2,directly above the uppermost precipitate-trough 0 therein. A pipe 26, which is disposed in the condensing-chamber 23, establishes communication between the steamspaces of the upperand lower compartments, this pipe allowing steam to pass from the upper compartment to the lower, as will be understood. The condensing-chamber 23 is here shown as providedin one side with an opening 27 and a closure 28 therefor, whereby access maybe obtained to the interior of the said condensing-chamber to enable the same to be readily cleaned.

Exhaust-steam from the engine is introduced into the upper compartment through the connection 29 and passes from the upper compartment to the lower compartment through the pipe 26 in the condenser 23. The lower compartment is provided with a discharge connection 30 for the exhaust-steam. It will be understood that the water in the condenser 23 serves to condense the steam as it passes through the pipe 26 and that the feed-water which enters the upper compartment through the pipe 25 is discharged onto the uppermost pricipitate-trough 6, first fills the same, then overflows into the lower precipitate-trough 6, then passes into the trap forming the bottom of the uppercompartment, then passes through the pipe 5 into the lower compartinent,being caught first by the uppermost precipitate-trough 14-, caused to fill each.

of said troughs in succession, then to pass into the lower portion of the lower compartment, from thence through the filter-ch amber 8, and finally through the supplemental filter-chamber 17 before it is fed to the boiler. The impurities are caused to settle in the said precipitate-troughs and in the bottoms of the upper and lower compartments, so that the water is eifectually ridden thereof. Such impurities as fail to be thus precipitated are an rested in the filter-chambers, so that the water is entirely purified before it is supplied to the boiler. It will be understood that the feed-water during its passage through the apparatus is effectually heated by the exhauststeam, the course of which has been hereinbefore indicated.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily apparent, it is thought,witho ut requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. A feed-water heater having a plurality of communicating compartments, means to supply exhaust-steam to one of said compartments, a conduit to establish steam communication between the said compartments, and means to supply feed-water to one of said compartments, the said feed-water-supplying means including a condenser in which the steam-conduit between the compartments is disposed,whereby the feed-water is employed to condense the steam as the latter passes from one compartment to another, substantially as described.

2. A feed-water heater having an upper compartment and a lower compartment, said upper compartment having an overflow-trap in its lower side, discharging into the lower compartment, means to supply steam to the upper compartment, a condenser having means to supply feed water thereto, and means'to conduct feed-water therefrom to the upper compartment, and a conduit to establish steam communication between the upper and lower compartments, said conduit passing through said condenser, substantially as described.

3. A feed-Water heater having an upper compartment, the bottom of which forms an overflow-trap, a lower compartment fed with.

water by said trap, means to supply the upper compartment with steam, means to esmy hand in presence of two subscribing wittablish steam communication between the up nesses.

per and lower compartments, and a filter inthe latter through which the water passes as 5 it is discharged therefrom, substantially as described.
